The aim of the present study was to investigate the morphological, histological, andhistochemical structures of the esophagus and stomach in small Indian mongoose at anatomy andhistology laboratory/ Veterinary Medicine College / Basra University in Basra/ Iraq. The currentstudy was conducted on six local healthy adult male mongoose directly . Morphological resultsreleaved that the esophagus is elastic muscular fibrous tube connects between pharynx andstomach. It consists from three parts; cervical, thoracic, and short abdominal part.The stomachappeared as simple type with shape of letter (J),and had three regions (cardiac, fundus, andpyloric region), two curvatures, and two openings. The mean length and width of esophagus andstomach (15cm, 0.5 cm) and (6.5 cm, 2cm cardiac, 1.5 cm fundus, and pyloric 1 cm in width)respectively. The histological study result showed the esophagus and stomach comprised fourlayers; mucosa, sub-mucosa, muscularis, and adventitia or serosa.Microscopic examination of esophagus revealed that the mucosal layer lined with thin stratifiedsquamous keratinized epithelium tissue. The gastric mucosa lined by simple columnar epitheliumwith goblet cells.This study showed the positive reaction for periodic acid Schiff (PAS)stain in esophagus andstomach , when appear red purple colour for mucin in the mucosa layer for them .
